Open a SLDPRT file
in OrcaSlicer.

Updated 2026-10-01

OrcaSlicer cannot open SLDPRT files: SOLIDWORKS parts are not among the formats it imports. Convert it to 3MF below, then open the .3mf in OrcaSlicer. OrcaSlicer opens a 3MF with its units and objects intact, ready to slice.

Can OrcaSlicer open SLDPRT files?
OrcaSlicer cannot open SLDPRT files: SOLIDWORKS parts are not among the formats it imports. Checked against OrcaSlicer's own documentation on 2026-10-01.
Why 3MF?
OrcaSlicer reads 3MF, and 3MF records units and separate objects, so the part arrives at the right size. It is a mesh, which is what OrcaSlicer works with anyway.
Is the conversion free?
Yes. Without an account, 5 conversions a day are free, with no card and nothing to install.
